Sleep Intervention to Enhance Cognitive Status and Reduce Beta-Amyloid (SIESTA)

Start: August 27, 2019
End: January 2023
Enrollment: 200

What Is This Study About?

This study will investigate the effects of a sleep intervention on improving cognitive function in older adults with insomnia. The training is designed to improve sleep by addressing a person's sleep environment, schedules, behaviors, and thoughts. Participants will be randomly assigned to weekly one-hour personal training sessions or stretching and thinking activities for six weeks. Participants in the sleep training group will also maintain a sleep diary, and some will undergo brain imaging to examine the effects of training on reducing the accumulation of proteins associated with Alzheimer's disease. Researchers will measure changes in cognitive function.
